The synopsis for the series says: "This is a sisterhood full of in-jokes, hand-me-down resentments and more than a few old wounds. But their DNA, history and shared love of power ballads keep the Walsh sisters together in the face of heartbreak, grief, addiction and parenthood."
As well as starring in the series, Preissner has also adapted the novels, writing four of the episodes while Kefi Chadwick (Rivals) has written the other two.
Aidan Quinn (Rematch) and Carrie Crowley (Hope Street) also play central roles in the series, as Daddy and Mammy Walsh.

When the series was first announced, Keyes said in a statement: "This is SO exciting!!!! I'm beside myself! I love the scripts; they've really kept the spirit of the books. It's been almost impossible to keep this a secret and it's a great feeling that the news is now out in the world."
The Walsh Sisters will arrive on BBC iPlayer at 6am on Saturday 21 February, and will air on BBC One from 9:15pm that night.
